CHAIN BRUSH non STILLS.

Application filed January 14, 1926. serial No. 81,337.

described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims.

In the drawings; 4

Figure 1 is a view in elevation and partly in section of a still, showing my improved brushing apparatus therein.

Figure 2 is a fragmentary perspective view of the brushing apparatus.

Figure 3 is a transverse sectional view of the shaft and head, showing the manner of assembling the rods therewith.

Figure 4 is a transverse sectional view of one of the heads, showing how the clips are attached thereto..

Referring to the drawings bynumerals, l designates the brick foundation upon which is mounted the still 2: this still 2 is provided with domes to which are connected the pipe line 4. the pipe line being run through the cooler box 5.

In the still 2 is "ournalled a horizontal shaft 6, and carried by the shaft 6 are a pair of brush devices. .Each brush device includes two vertical rods '1' that extend through the shaft 6 (Fig. 3) and the lower .end of these rods also extends through the horizontal head 8. Horizontal rivets 9 extend through the head 8. and through the lower ends of the rods 7, for fastening these parts together.

Spring clips 10 are employed, each clip being provided with inturn ends that extend into the head 8 (Fig. 4). A primary depending chain 11 is fastened to the clips 10, there being illustrated in the drawings four clips used on each brush, but any desired number of clips as'well as the depending loops of the chain may be employed.

Under the clips, 10, intermediate the ends of the head 8are arranged'aux-ili'ary chains 12. These auxiliary chainsare connected at their ends to the depending primary chain 11 and at the end clips. I provide depending short chains 13. and 13. I provide a broad scraping or rubbing element that engagessubstantially the entire inner fzn of the still 2 when the shaft. (3 is rotated. i

A short connecting chain H (Fig. 1) connects the chains 11 of the two bru he making the brushes of the apparatus what might be termed a uniform structure that reaches from end of the still to the other end, as clearly shown. whereby the efficiency of my brushing apparatus is nearly perfect.

A handle or crank arm 15 is fixedly secured to shaft ti, and a rod or pitman 16 is pivotally attached at 17 to crank arm 1."). By imparting power-to pitman 16. to turn or rotate crank arm 15 and shaft 6, the

brushes carried by said shaft ti will be revolved in still :2, of the still.

'hile I have described the preferred enibodiment of my invention and illustrated the same in the accompanying drawings,

to brush or clean the inside certain minor alterations or changes may appear to one skilled in the art to which this invention relates. during the extensive manu-- facture of the same. and I', therefore, reserve the right to make such alterations or changes as shallfairly fall within the scope of the appended claims.

What I claim is:

1. A chain brush for stills, comprising a head, spring clips having endsin said head, and a chain attached to said spring clips.

2. A chain brush for stills, comprising a head, a plurality of spring clips having their ends embedded in said head, and chains attached to said spring clips and normally depending therefrom.

3. A chain brush for stills, comprising heads, a plurality of depending clips with inturned ends. said inturned ends embedded in said heads, chains suspended in a draped or depending position from all of said clips, short end chains suspended from the clips at the outer endsof said heads, and an intermediate chain between the heads and connected at its ends to the chains depending-from the spring clips.

In' testimony whereof I hereunto. aflix my signature.

, WILLIAM KNAPP.
